The water heater thread reminded me that I've been putting off some decisions - so thanks to all for the info on tankless water heaters. I've been considering one of those for a couple of reasons, primarily energy efficiency. The unlimited hot water will be nice as our three boys start consuming more of it! I've heard the new gas units are so efficient that they use PVC for the exhaust vent. Our water heater is about 12 years old. It was replaced under our home buyers warranty, so I am sure it was the lowest quality available...as a result I figure I'm getting near the end of its life expectancy. I didn't know where were outdoor units - that might work for me.
Has anyone run across data on reliability/lifespan of the tankless gas heaters? They are pretty pricey - should they outlive a conventional tank?
BTW, have gas, so I'm also considering putting in a propane tank behind my house. My first floor heat pump is also near (past) its life expectancy...so I was considering a duel-fuel pump for better efficiency in the winter. The heat pump is also in a closet in my workshop, so the gas line doesn't have to run very far. It is also right below the kitchen, making a gas range a possibility. I'm trying to consider them all together, since (I assume) there is considerable expense in adding a tank and associated lines.
I'm open to any advice - I've only barely researched this at all.
As an aside, the current water tank is in my workshop...so a smaller tankless unit means a few more sq ft in my small shop
